FORMS OF CARBAMATE DERIVATIVES AND RELATED USES

RELATED APPLICATION

[001] This application claims priority to U.S. Provisional Patent Application No. 63/413,036, filed October 4, 2022, the entire content of which is hereby incorporated by reference.

BACKGROUND

[002] Autoimmune diseases are associated with the overproduction of proinflammatory factors. One of them is interleukin- 1 (IL-1), produced by activated macrophages, monocytes, fibroblasts, and other components of the innate immune system like dendritic cells. IL-1 is involved in a variety of cellular activities, including cell proliferation, differentiation and apoptosis (Masters, S. L., et. al., Annu. Rev. Immunol. 2009. 27:621-68).

[003] In humans, 22 NLR proteins are divided into four NLR subfamilies according to their N- terminal domains. NLRA contains a CARD-AT domain, NLRB (NAIP) contains a BIR domain, NLRC (including NODI and NOD2) contains a CARD domain, and NLRP contains a pyrin domain. Multiple NLR family members are associated with inflammasome formation.

[004] Although inflammasome activation appears to have evolved as an important component of host immunity to pathogens, the NLRP3 inflammasome is unique in its ability activate in response to endogenous sterile danger signals. Many such sterile signals have been elucidated, and their formation is associated with specific disease states. For example, uric acid crystals found in gout patients are effective triggers of NLRP3 activation. Similarly, cholesterol crystals found in atherosclerotic patients can also promote NLRP3 activation. Recognition of the role of sterile danger signals as NLRP3 activators led to IL-1 and IL- 18 being implicated in a diverse range of pathophysiological indications including metabolic, physiologic, inflammatory, hematologic and immunologic disorders.

DETAILED DESCRIPTION

[028] Autoimmune diseases are associated with the overproduction of proinflammatory factors. One of them is interleukin- 1 (IL-1), produced by activated macrophages, monocytes, fibroblasts, and other components of the innate immune system like dendritic cells, involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis (Masters, S. L., et al. Annu. Rev. Immunol. 2009. 27:621-68).

[029] Cytokines from the IL-1 family are highly active and, as important mediators of inflammation, primarily associated with acute and chronic inflammation (Sims, J. et al., Nature Reviews Immunology 10, 89-102 (February 2010)). The overproduction of IL-1 is considered to be a mediator of some autoimmune and autoinflammatory diseases. Autoinflammatory diseases are characterised by recurrent and unprovoked inflammation in the absence of autoantibodies, infection, or antigen-specific T lymphocytes.

[030] Proinflammatory cytokines of the IL-1 superfamily include IL- la, IL-ip, IL- 18, and IL- 36a, P, A. and are produced in response to pathogens and other cellular stressors as part of a host innate immune response. Unlike many other secreted cytokines, which are processed and released via the standard cellular secretory apparatus consisting of the endoplasmic reticulum and Golgi apparatus, IL-1 family members lack leader sequences required for endoplasmic reticulum entry and thus are retained intracellularly following translation. In addition, IL-ip, IL- 18, and IL-36a, P, A. are synthesised as procytokines that require proteolytic activation to become optimal ligands for binding to their cognate receptors on target cells.

[031] In the case of IL- la, IL-ip and IL- 18, it is now appreciated that a multimeric protein complex known as an inflammasome is responsible for activating the proforms of IL-ip and IL- 18 and for release of these cytokines extracellularly. An inflammasome complex typically consists of a sensor molecule, such as an NLR (Nucleotide-Oligerimisation Domain (NOD)-like receptor), an adaptor molecule ASC (Apoptosis-associated speck-like protein containing a CARD (Caspase Recruitment Domain)) and procaspase- 1. In response to a variety of “danger signals”, including pathogen-associated molecule patterns (PAMPs) and danger associated molecular patterns (DAMPs), subunits of an inflammasome oligomerise to form a supramolecular structure within the cell. PAMPs include molecules such as peptidoglycan, viral DNA or RNA and bacterial DNA or RNA. DAMPs, on the other hand, consist of a wide range of endogenous or exogenous sterile triggers including monosodium urate crystals, silica, alum, asbestos, fatty acids, ceramides, cholesterol crystals and aggregates of beta-amyloid peptide. Assembly of an inflammasome platform facilitates autocatalysis of procaspase- 1 yielding a highly active cysteine protease responsible for activation and release of pro-IL-ip and pro-IL-18. Thus, release of these highly inflammatory cytokines is achieved only in response to inflammasome sensors detecting and responding to specific molecular danger signals.

[032] In humans, 22 NLR proteins are divided into four NLR subfamilies according to their N- terminal domains. NLRA contains a CARD-AT domain, NLRB (NAIP) contains a BIR domain, NLRC (including NODI and NOD2) contains a CARD domain, and NLRP contains a pyrin domain. Multiple NLR family members are associated with inflammasome formation including NLRP1, NLRP3, NLRP6, NLRP7, NLRP12 and NLRC4 (IPAF).

[033] Two other structurally distinct inflammasome structures containing a PYHIN domain (pyrin and HIN domain containing protein) namely Absent in Melanoma 2 (AIM2) and IFNX- inducible protein 16 (IFI16) (Latz et al., Nat Rev Immunol 2013 13(6) 397-311) serve as intracellular DNA sensors. Pyrin (encoded by the MEFV gene) represents another type of inflammasome platform associated with proIL-10 activation (Chae et al., Immunity 34, 755-768, 2011).

[034] Requiring assembly of an inflammasome platform to achieve activation and release of IL- 10 and IL- 18 from monocytes and macrophages ensures their production is carefully orchestrated via a 2-step process. First, the cell must encounter a priming ligand (such as the TLR4 receptor ligand LPS, or an inflammatory cytokine such as TNFa) which leads to NFkB dependent transcription of NLRP3, pro-IL-ip and pro-IL-18. The newly translated procytokines remain intracellular and inactive unless producing cells encounter a second signal leading to activation of an inflammasome scaffold and maturation of procaspase- 1.

[035] In addition to proteolytic activation of pro-IL-ip and pro-IL-18, active caspase- 1 also triggers a form of inflammatory cell death known as pyroptosis through cleavage of gasdermin- D. Pyroptosis allows the mature forms of IL-ip and IL- 18 to be externalised along with release of alarmin molecules (compounds that promote inflammation and activate innate and adaptive immunity) such as high mobility group box 1 protein (HMGB1), IL-33, and IL- la.

[036] Although inflammasome activation appears to have evolved as an important component of host immunity to pathogens, the NLRP3 inflammasome is unique in its ability activate in response to endogenous and exogenous sterile danger signals. Many such sterile signals have been elucidated, and their formation is associated with specific disease states. For example, uric acid crystals found in gout patients are effective triggers of NLRP3 activation. Similarly, cholesterol crystals found in atherosclerotic patients can also promote NLRP3 activation. Recognition of the role of sterile danger signals as NLRP3 activators led to IL- 10 and IL- 18 being implicated in a diverse range of pathophysiological indications including metabolic, physiologic, inflammatory, hematologic and immunologic disorders.

[037] A link to human disease is best exemplified by discovery that mutations in the NLRP3 gene which lead to gain-of-function confer a range of autoinflammatory conditions collectively known as cryopyrin-associated periodic syndromes (CAPS) including familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and Neonatal onset multisystem inflammatory disease (NOMID) (Hoffman et al., Nat. Genet. 29(3) (2001) 301-305). Likewise, sterile mediator-induced activation of NLRP3 has been implicated in a wide range of disorders including joint degeneration (gout, rheumatoid arthritis, osteoarthritis), cardiometabolic (type 2 diabetes, atherosclerosis, hypertension), Central Nervous System (Alzheimer’s Disease, Parkinson’s disease, multiple sclerosis), gastrointestinal (Crohn’s disease, ulcerative colitis), lung (chronic obstructive pulmonary disease (COPD), asthma, idiopathic pulmonary fibrosis) and liver (fibrosis, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis (NASH)). It is further believed that NLRP3 activation promotes kidney inflammation and thus contributes to chronic kidney disease (CKD).

[038] Current treatment options for diseases where IL-1 is implicated as a contributor to pathogenesis include the IL-1 receptor antagonist anakinra, an Fc-containing fusion construct of the extracellular domains of the IL-1 receptor and IL-1 receptor accessory protein (rilonacept) and the anti-IL-10 monoclonal antibody canakinumab. For example, canakinumab is licensed for CAPS, Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS), Hyperimmunoglobulin D Syndrome (HIDS)/Mevalonate Kinase Deficiency (MKD), Familial Mediterranean Fever (FMF) and gout.

[039] Some small molecules have been reported to inhibit function of the NLRP3 inflammasome. Glyburide, for example, is a specific inhibitor of NLRP3 activation, albeit at micromolar concentrations which are unlikely attainable in vivo. Non-specific agents such as parthenolide, Bay 11-7082, and 3,4-methylenedioxy-0-nitrostyrene are reported to impair NLRP3 activation but are expected to possess limited therapeutic utility due to their sharing of a common structural feature consisting of an olefin activated by substitution with an electron withdrawing group; this can lead to undesirable formation of covalent adducts with proteinbearing thiol groups. A number of natural products, for example 0-hydroxybutyrate, sulforaphane, quercetin, and salvianolic acid, also are reported to suppress NLRP3 activation. Likewise, numerous effectors/modulators of other molecular targets have been reported to impair NLRP3 activation including agonists of the G-protein coupled receptor TGR5, an inhibitor of sodium-glucose co-transport epigliflozin, the dopamine receptor antagonist A-68930, the serotonin reuptake inhibitor fluoxetine, fenamate non-steroidal anti-inflammatory drugs, and the 0-adrenergic receptor blocker nebivolol. Utility of these molecules as therapeutics for the chronic treatment of NLRP3 -dependent inflammatory disorders remains to be established.

[040] The disclosure relates to compounds useful for the specific modulation of NLRP3- dependent cellular processes. In particular, compounds with improved physicochemical, pharmacological and pharmaceutical properties to existing NLRP3 -modulating compounds are desired.

High-throughput assays can use one or more different assay techniques including, but not limited to, those described below.

[0115] Various in vitro or in vivo biological assays may be suitable for detecting the effect of the compounds of the present disclosure. These in vitro or in vivo biological assays can include, but are not limited to, enzymatic activity assays, electrophoretic mobility shift assays, reporter gene assays, in vitro cell viability assays, and the assays described herein.

[0116] In some embodiments, the biological away is a biological away testing inhibitory activity against IL- 10 release upon NLRP3 activation in peripheral blood mononuclear cells (PBMC).

[0117] In some embodiments, the biological assay is a PBMC IC50 Determination Assay.

[0119] In some embodiments, PBMC is isolated and seeded into the wells of a plate and incubated for a period of time (e.g., for 3 hours with a lipopolysaccharide). Following incubation, the medium is exchanged and the compound added to the well (e.g., a compound of the present disclosure) and the cells may be incubated. Next, the cells are stimulated (e.g., with ATP or nigericin) and the cell culture media are collected for analysis. [0120] In some embodiments, the release of IL- 10 into the media is determined by a quantitative detection of IL-10 in the media (e.g., using ELISA).

Pharmaceutical Compositions

[0123] In some aspects, the present disclosure provides pharmaceutical compositions comprising a crystalline form of Compound A described herein, and one or more pharmaceutically acceptable carrier or excipient.

[0124] The pharmaceutical compositions containing active compounds of the present disclosure may be manufactured in a manner that is generally known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. Pharmaceutical compositions may be formulated in a conventional manner using one or more pharmaceutically acceptable carrier comprising one or more excipient and/or auxiliary that facilitates processing of the active compound into preparations that can be used pharmaceutically. A person of skill in the art would understand that the appropriate formulation may be dependent upon the route of administration chosen.

[0125] Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers may include physiological saline, bacteriostatic water, Cremophor EL (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringeability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol and sorbitol, and sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

[0126] Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile- filtered solution thereof.

[0127] Oral compositions may include one or more inert diluent or one or more edible pharmaceutically acceptable carrier. They can be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound in the fluid carrier is applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. 1 [0128] For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser, which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.

[0129] Systemic administration can also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art.

[0130] The active compounds can be prepared with one or more pharmaceutically acceptable carrier that may protect the compound against rapid elimination from the body, such as a controlled release formulation, including an implant and microencapsulated delivery system. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art.

[0131] It may be especially advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the disclosure are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved.

[0132] In therapeutic applications, the dosages of the pharmaceutical compositions used in accordance with the disclosure vary depending on the agent, the age, weight, and clinical condition of the recipient patient, and the experience and judgment of the clinician or practitioner administering the therapy, among other factors affecting the selected dosage. Generally, the dose should be sufficient to result in slowing, and preferably regressing, the symptoms of the disease and also preferably causing complete regression of the disease.

[0133] It is understood that the pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration. Methods of Use

[0183] As used herein, the term “pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes excipient that is acceptable for veterinary use as well as human pharmaceutical use. A “pharmaceutically acceptable excipient” as used in the specification and claims may include both one and more than one such excipient.

[0184] It is to be understood that a pharmaceutical composition of the disclosure is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., ingestion), inhalation, transdermal (topical), and transmucosal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulphite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates, and agents for the adjustment of tonicity such as sodium chloride or dextrose. The pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

[0185] It is to be understood that a compound or pharmaceutical composition of the disclosure can be administered to a subject in many of the well-known methods currently used for chemotherapeutic treatment. For example, a compound of the disclosure may be injected into the blood stream or body cavities or taken orally or applied through the skin with patches. The dose chosen should be sufficient to constitute effective treatment but not so high as to cause unacceptable side effects. The state of the disease condition (e.g, a disease or disorder disclosed herein) and the health of the patient should preferably be closely monitored during and for a reasonable period after treatment. [0186] As used herein, the term “therapeutically effective amount”, refers to an amount of a pharmaceutical agent to treat, ameliorate, or prevent an identified disease or condition, or to exhibit a detectable therapeutic or inhibitory effect. The effect can be detected by any assay method known in the art. The precise effective amount for a subject will depend upon the subject’s body weight, size, and health; the nature and extent of the condition; and the therapeutic or combination of therapeutics selected for administration. Therapeutically effective amounts for a given situation can be determined by routine experimentation that is within the skill and judgment of the clinician.

[0187] As used herein, the term “effective amount”, refers to an amount of a pharmaceutical agent to treat or ameliorate an identified disease or condition, or to exhibit a detectable therapeutic or inhibitory effect. The effect can be detected by any assay method known in the art. The precise effective amount for a subject will depend upon the subject’s body weight, size, and health; the nature and extent of the condition; and the therapeutic or combination of therapeutics selected for administration. Therapeutically effective amounts for a given situation can be determined by routine experimentation that is within the skill and judgment of the clinician.

[0188] It is to be understood that, for any compound, the therapeutically effective amount or effective amount can be estimated initially either in cell culture assays, e.g., of neoplastic cells, or in animal models, usually rats, mice, rabbits, dogs, or pigs. The animal model may also be used to determine the appropriate concentration range and route of administration. Such information can then be used to determine useful doses and routes for administration in humans. Therapeutic/prophylactic efficacy and toxicity may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., EDso (the dose therapeutically effective in 50% of the population) and LDso (the dose lethal to 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, and it can be expressed as the ratio, LD50/ED50. Pharmaceutical compositions that exhibit large therapeutic indices are preferred. The dosage may vary within this range depending upon the dosage form employed, sensitivity of the patient, and the route of administration.

[0189] Dosage and administration are adjusted to provide sufficient levels of the active agent(s) or to maintain the desired effect. Factors which may be taken into account include the severity of the disease state, general health of the subject, age, weight, and gender of the subject, diet, time and frequency of administration, drug combination(s), reaction sensitivities, and tolerance/response to therapy.

[0190] The pharmaceutical compositions containing a crystalline form of Compound A may be manufactured in a manner that is generally known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilising processes. Pharmaceutical compositions may be formulated in a conventional manner using one or more pharmaceutically acceptable carrier comprising excipients and/or auxiliaries that facilitate processing of a crystalline form of Compound A into preparations that can be used pharmaceutically. The appropriate formulation is dependent upon the route of administration chosen.

[0191] The crystalline form of Compound A can be prepared with one or more pharmaceutically acceptable carrier that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including an implant and microencapsulated delivery system. [0192] It is to be understood that the pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration.

EXAMPLES

Instrument and Methodology Details

[0231] The instrument and methodology details for the experiments carried out in the examples are described herein.

X-Ray Powder Diffraction (XRPD)

[0232] Broker AXS C2 GADDS:

[0233] XRPD diffractograms were collected on a Bruker AXS C2 GADDS diffractometer using Cu Koc radiation (40 kV, 40 mA), an automated XYZ stage, a laser video microscope for auto-sample positioning and a Vantec-5002-dimensional area detector. X-ray optics consists of a single Gobel multilayer mirror coupled with a pinhole collimator of 0.3 mm. The beam divergence, i.e. the effective size of the X-ray beam on the sample, was approximately 4 mm. A 0-0 continuous scan mode was employed with a sample - detector distance of 20 cm which gives an effective 20 range of 1.5° - 32.5°. Typically, the sample was exposed to the X-ray beam for 120 seconds. The software used for data collection and analysis was GADDS for Win7/XP and Diffrac Plus EVA respectively. [0234] Ambient conditions: Samples run under ambient conditions were prepared as flat plate specimens using powder as received without grinding. Samples were prepared and analysed on a glass slide, by lightly pressed the powder to obtain a flat surface for analysis.

[0235] Non-ambient conditions: For variable temperature (VT-XRPD) experiments samples were mounted on an Anton Paar DHS 900 hot stage at ambient conditions. The sample was then heated to the appropriate temperature at 20 °C/min and subsequently held isothermally for 1 minute before data collection. Samples were prepared and analysed on a silicon wafer mounted to the hot stage using a heat-conducting paste.

[0236] Bruker AXS D8 Advance:

[0237] XRPD diffractograms were collected on a Bruker D8 diffractometer using Cu Ka radiation (40 kV, 40 mA) and a 0-20 goniometer fitted with a Ge monochromator. The incident beam passes through a 2.0 mm divergence slit followed by a 0.2 mm anti-scatter slit and knife edge. The diffracted beam passes through an 8.0 mm receiving slit with 2.5° Seller slits followed by the Lynxeye Detector. The software used for data collection and analysis was Diffrac Plus XRD Commander and Diffrac Plus EVA respectively.

[0238] Samples were run under ambient conditions as flat plate specimens using powder as received. The sample was prepared on a polished, zero-background (510) silicon wafer by gently pressing onto the flat surface or packed into a cut cavity. The sample was rotated in its own plane.

[0239] The details of the standard Pharmorphix data collection method are:

• Angular range: 2 to 42° 20

• Step size: 0.05° 20

• Collection time: 0.5 s/step (total collection time: 6.40 min)

[0240] When required other methods for data collection are used with details as follows:

[0241] PANalytical Empyrean:

[0242] XRPD diffractograms were collected on a PANalytical Empyrean diffractometer using Cu Ka radiation (45 kV, 40 mA) in transmission geometry. A 0.5° slit, 4 mm mask and 0.04 rad Seller slits with a focusing mirror were used on the incident beam. A PIXcel 3D detector, placed on the diffracted beam, was fitted with a receiving slit and 0.04 rad Seller slits. The software used for data collection was X’Pert Data Collector using X’Pert Operator Interface. The data were analysed and presented using Diffrac Plus EVA or HighScore Plus. Samples were prepared and analysed in either a metal or Millipore 96 well-plate in transmission mode. X-ray transparent film was used between the metal sheets on the metal well-plate and powders (approximately 1 - 2 mg) were used as received. The Millipore plate was used to isolate and analyse solids from suspensions by adding a small amount of suspension directly to the plate before filtration under a light vacuum.

[0243] The scan mode for the metal plate used the gonio scan axis, whereas a 20 scan was utilised for the Millipore plate.

[0244] The details of the standard screening data collection method are:

• Angular range: 2.5 to 32.0° 20

• Step size: 0.0130° 20

• Collection time: 12.75 s/step (total collection time of 2.07 min)

Nuclear Magnetic Resonance (NMR)

[0245] NMR spectra were collected on a Bruker 400 MHz instrument equipped with an auto-sampler and controlled by a DRX400 console. Samples were prepared in DMSO-t/e solvent, unless otherwise stated. Automated experiments were acquired using ICON-NMR configuration within Topspin software, using standard Bruker-loaded experiments ( 1 H). Off-line analysis was performed using ACD Spectrus Processor.

Differential Scanning Calorimetry (DSC)

[0246] TA Instruments Q2000: DSC data were collected on a TA Instruments Q2000 equipped with a 50 position auto-sampler. Typically, 0.5 - 3 mg of each sample, in a pin-holed aluminium pan, was heated at 10 °C/min from 25 °C to 260 °C. A purge of dry nitrogen at 50 ml/min was maintained over the sample. Modulated temperature DSC was carried out using an underlying heating rate of 2 °C/min and temperature modulation parameters of ±0.636 °C (amplitude) every 60 seconds (period). The instrument control software was Advantage for Q Series and Thermal Advantage and the data were analysed using Universal Analysis or TRIOS. Thermo-Gravimetric Analysis (TGA)

[0247] TA Instruments Q500: TGA data were collected on a TA Instruments Q500 TGA, equipped with a 16 position auto-sampler. Typically, 5 - 10 mg of each sample was loaded onto a pre-tared aluminium DSC pan and heated at 10 °C/min from ambient temperature to 350 °C. A nitrogen purge at 60 ml/min was maintained over the sample. The instrument control software was Advantage for Q Series and Thermal Advantage and the data were analysed using Universal Analysis or TRIOS.

Polarised Light Microscopy (PLM)

[0248] Leica LM/DM Polarised Light Microscope: Samples were analysed on a Leica LM/DM polarised light microscope with a digital video camera for image capture. A small amount of each sample was placed on a glass slide, with or without immersion oil, and covered with a glass slip. The sample was viewed with appropriate magnification and partially polarised light, coupled to a X false-colour filter. Images were captured using StudioCapture or Image ProPlus software.

Scanning Electron Microscopy (SEM)

[0249] Data were collected on a Phenom Pro Scanning Electron Microscope. A small quantity of sample was mounted onto an aluminium stub using conducting double-sided adhesive tape. A thin layer of gold was applied using a sputter coater (20 mA, 120 s).

Gravimetric Vapour Sorption (GVS)

[0250] Sorption isotherms were obtained using a SMS DVS Intrinsic moisture sorption analyser, controlled by DVS Intrinsic Control software. The sample temperature was maintained at 25 °C by the instrument controls. The humidity was controlled by mixing streams of dry and wet nitrogen, with a total flow rate of 200 ml/min. The relative humidity was measured by a calibrated Rotronic probe (dynamic range of 1.0 - 100 %RH), located near the sample. The weight change, (mass relaxation) of the sample as a function of %RH was constantly monitored by a microbalance (accuracy ±0.005 mg). [0251] Typically, 5 - 30 mg of sample was placed in a tared mesh stainless steel basket under ambient conditions. The sample was loaded and unloaded at 40 %RH and 25 °C (typical room conditions). A moisture sorption isotherm was performed as outlined below (2 scans per complete cycle). The standard isotherm was performed at 25 °C at 10 %RH intervals over a 0 - 90 %RH range. Typically, a double cycle (4 scans) was carried out. Data analysis was carried out within Microsoft Excel using the DVS Analysis Suite.

[0252] The sample was recovered after completion of the isotherm and re-analysed by XRPD.

[0255] Data were collected on a Rigaku Oxford Diffraction XtaLAB Synergy-S diffractometer equipped with a dualflex source (Cu at Zero), HyPix-6000HE detector and an Oxford Cryosystems Cobra cooling device. The data were collected using Cu Ka radiation as stated in the experimental tables. Structures were solved and refined using the Shelx suite of programs and OLEX was used as an interface to view the structures with and produce figures. Unless otherwise stated, hydrogen atoms attached to carbon were placed geometrically and allowed to refine with a riding isotropic displacement parameter. A reference diffractogram for the crystal structure was generated using Mercury.

Example 1. Exemplary Preparation of Form 1. [0256] Compound A was dissolved in IPA (8.6x) and the temperature raised to 50 °C. Seeds (O.Olx) were added to the reaction at 40 °C. The reaction kept at 40 °C for 2 hours then 30 °C for 2 hours. n-Heptane slowly was added (21x) and the mixture stirred a further 9 hours at 30 °C. The reaction was then cooled (5 °C) and filtered. The cake was washed with n-Heptane to yield Form 1 (90% yield).

[0257] Form 1 was characterized using a wide range of techniques to investigate the solid form and chemical properties (FIGS. 1-6B). A summary of the results is shown below:

Table A

[0258] Form 1 is anhydrous and thermally stable as shown by thermal analysis. TGA showed no weight loss before degradation, which occurred from -220 °C and DSC showed a melt endotherm onset at 128.7 °C. Form 1 is non-hygroscopic, GVS showed an increase of < 0.1 % between 40-90 % RH and no hysteresis and remained as Form 1. The sample was 99.4 % pure by HPLC and ion chromatography showed no residual cations/anions were present in the sample. The particles in the supplied batch were of needle morphology of various sizes with an average -150 pm. The Raman spectrum was collected as reference showing multiple signals. The scanning IC showed no trace of cation or anions present.

Example 2. Exemplary Preparation of Form 2.

[0259] Form 1 (500 mg) was dissolved in 30 ml 2-methyl- 1 -propanol at 5 °C. Heptane (30 ml) was added and stirred for 10 minutes, after additional heptane was added (30 ml) and stirred overnight giving a white precipitate. The suspension was filtered under vacuum and dried for 30 minutes. XRPD analysis showed this to be Form 1. The mother liqueurs were concentrated by evaporation and seeded with Form 2 then evaporated to dryness. Yield: 63.9 %.

[0260] Form 2 was characterized using a wide range of techniques to investigate the solid form and chemical properties (FIGS. 7-1 IB). A summary of the results is shown below. Table B and Table C showed results of characterization of two batches of Form 2.

Table B

[0261] Analysis showed crystalline Form 2 by XRPD, and high purity by HPLC (99.2 %). 'H- NMR analysis matched the expected structure and thermal analysis showed no weight loss before degradation by TGA, and a sharp endotherm onset - 129.3 °C (89 J/g). Form 2 was found to be stable at elevated storage at 25 °C/ 97 % RH and 40 °C/ 75% RH for 1 week.

[0262] Analysis by XRPD showed Form 2, and the 'H-NMR matched the expected structure. Thermal analysis showed no weight loss before degradation which started from ~ 190 °C and no thermal events were observed before a large sharp endotherm with an onset temperature at -128.4 °C (89.4 °J/g) by DSC. Microscopy showed the particles to be needles between 50-75 pm. Form 2 was found to be non-hygroscopic with no hysteresis by GVS and remained Form 2 by XRPD after the GVS experiment. The solid form was also found to be stable at elevated conditions.

Example 3. Solvent and Solubility Study of Morphic Forms

[0263] Solubility of Form 1 was measured in several single solvents using Form 2 as starting material, respectively. Results showed Form 2 converted to Form 1 in all selected solvents except for water after slurry at 20-25 °C. Form 1 exhibited good solubility in MeOH, Acetone, MEK, EtOAc and IP Ac, moderate solubility in EtOH and IP A, and poor solubility in n-heptane and water. Thus, MeOH, Acetone, MEK, EtOAc and IP Ac were selected for further chemical stability evaluation before starting solubility test with anti-solvents.

[0264] Solubility of Form 1 was further measured in IPAc/Heptane system with different ratio at 0-50 °C. Solubility data showed that a cooling and anti-solvent crystallization is an available design in this solvent system.

Example 4. Chemical Stability Evaluation of Morphic Forms.

[0265] Chemical stability of this compound was evaluated in MeOH, Acetone, MEK, EtOAc, and IP Ac at different temperature points. The table below showed that the compound was chemical stable in IP Ac at 50 °C for 24h. However, serious degradation was observed in MeOH and MEK and slight degradation occurred in Acetone and EtOAc after stirred for 23 h.

Example 5. Crystallization Study of Morphic Forms.

[0266] Crystallization process in IP Ac / n-heptane was conducted based on the solubility data. One batch experiment was carried out using 8 vol IP Ac for dissolution at 50 °C. Then, 2 vol heptane was charged to the ratio of 4/1 at 50 °C for producing supersaturation. After adding 1% seed and aging for 3 h, 22 vol heptane was dosed into the system in 8h at 50 °C. Then, the suspension was cooled down to 0-5 °C in 6 h. This process gave correct form with good purity, acceptable mother liquor loss and low residual solvent. However, some solid was observed sticking on the wall, which and might produce a lower solid yield. This may be due to the evaporation of solvent, leading to precipitation of solid on the wall during anti-solvent addition at high temperature.

[0267] Another batch crystallization experiment was performed at lower temperature to avoid solid-sticking. After dissolution in 8 vol IP Ac at 50 °C, the solution was cooled down to 40 °C for seeding. Then the contents was further cooled down to 30 °C for anti-solvent addition. The reactor was clean and no solid-sticking phenomenon. This optimized process gave good results as before.

[0268] A 20 g scale-up experiment was carried out followed with same process. Finally, scale-up experiment generated 96.5% solid yield, correct form, and hundreds ppm of residual solvent. Results showed this process was scaled-up successfully.
